I have been diagnosed "pre-diabetic" and I am overweight. I'm one of those "tried everything" dieters and Signos has given me, for the first time in my life, actual real-time emperical data - not just "try this and get back to me in 90 days to see if that impacted the issue". I get scientific data as the event is ocurring - not anecdotal guessing - to judge what meals work for me and also what should be avoided. I am finding out fascinating details of the impact of certain foods on my glucose/insulin response. This is a great thing!
